HIBAM \V. BUBLEE, OF DENVER, COLORADO. I

WAGON-JACK.

SPECIFICATION forming part of Letters PatentNo. 361,025, dated April 12,1887.

Application filed February 5, 1887. Serial No 226,632. (No model.)

To all whom it may concern:

Be it known that I, HIRAM W. RUBLEE, a citizen of the United States,residing at Denver, in the county of Arapahoe and State of Colorado,have invented certain new and useful Improvements in Wagon-Jacks, ofwhich the following is a specification, reference being had therein tothe accompanying drawings, in which similar letters refer tocorresponding parts.

Figure 1 is a side elevation of my improved jack, the same beinglowered. Fig. 2 is a side elevation showing thejack elevated. Fig. 3 isa front elevation of the jack in the position shown in Fig. 1. Figs. 4,5, and 6 are front, side, and top views,-respective1y, of the supportupon which the wagon-axle rests when my machine is in use. Figs. 7, 8,9, 10, 11, and 12 are designed to illustrate the construction and use ofspring J.

In the drawings, A is the base of the jack, to each side of which isbolted asuitabie standard, B. Standards B are attached to base A nearits rear extremity, the longer arm of said base being in front for thepurpose of giving the jack the required stability when in use, theweight of the wagon being always in front of said standards.

0 is a cam-lever, thebolt G forming its fulcrum.

D D are braces which support standards B.

E is alifting-bar supported between standards B by the bolts F F, whichpass through the slots E and E", said slots being shaped substantiallyas shown in the drawings.

Lifting-bar E is provided with the toothed plate H, shaped as shown, andupon which a support, I, rests, as shown in Fig. 1, said support beingshaped as shown in Figs. 4, 5, and 6, and provided with lugs 1 I, whichare received by the plate H.

J is a steel spring connecting lifting-bar E and lever 0, being attachedin any suitable manner to said parts, the object of said spring being todraw the lifting-bar into position in lowering the jack. A suitablemeans of attaching spring J to the parts connected by it is distinctlyshown in Figs. 11 and 12.

In the use of inyirnproved jack the support I may be raised and loweredupon toothed plate H at pleasure. This is an important feature of mydevice, and enables the operator 'to adjust the same quickly and easilyto correspond with the height of the wagon-axle, and in changing fromone wagon to another of different height. Support I is raised andlowered upon toothed plate H by taking support I in the hand and liftingits lugs out of the teeth or notches of plate H, and holding it so thatsaid lugs will not come in contact with said teeth until the requiredpoint on plate H is reached, when the lugs I are allowed to drop againinto the teeth of plate H.

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, 1s

In a wagon-jack, the lifting-bar E, provided with toothed plate H, incombination with adjustable support I, spring J, standard B, andcam-lever O, substantially as described, and 7 for the purposespecified.
